The Zen Nihon Budogu Renmei (which Eguchi Budogu & Eguchi Budo belong to) has noted that recently some makers have recently begun selling unsafe kendo equipment labeled as "light weight."  All kenshi, especially those who are new to the art, need to be aware that light weight alone does not constitute a good, or even a safe bogu!  For example- most good kotes weight roughly 300 to 400 grams; some new lightweight kotes only weigh 200 grams, far less than what is required for adequate protection. 

Look closely at what you intend to invest in.  If you can't see what it is you are going to buy, work out a deal with your bogu supplier to ship the item with the understanding that you may return it (Eguchi Budo honors returns, and is at many events across the US throughout the year, and can help).  Look at the same equipment used- find someone who bought what you are thinking about, and ask for their opinion.  Give particular attention to the men and kote, as they get the most abuse.  The kote gashira should have plenty of padding, and the kote buton should be able to absorb a sharp blow.  The men buton should be reinforced and provide good protection to the top of the head, and should fit so that all of your head is protected (if the buton is too short ront-to-back, the back of your head is vulnerable).  And as always, whenever in doubt, ask your sensei- he or she will give you the best advice possible, as they know your style and intentions.

Keep in mind that a bogu should be chosen based on both your ability AND intended use.  Eguchi Budo has been warning kenshi for years to not buy based on looks & style, but based on practicality, safety, and comfort.  If you are looking for a bogu set and plan on acting as motodachi often, then you ought to consider this when you purchase a bogu.  If you have a tendency to get hit a lot, do more keiko and get a more protective bogu.  If you are looking for the ultimate in light weight to get you through constant practices and long shiai, then a special lightweight bogu may be just what you are looking for.

The Jissen bogu set is a perfect example of how Tada Sangyo has listened to experienced kenshi who practice daily (Japanese riot police and kendo teams) to produce a bogu set tailored to their unique needs.  Make no mistake- the Jissen bogu set is light, but the weight savings are designed in all of the right places.  Tada has years of kendo equipment experience, and has utilized special construction techniques to make a bogu set that meets the needs of serious kenshi.  Is it perfect for everyone?  Absolutely not.  We would not recommend the Jissen for someone who simply goes to practice to be a motodachi, nor would we recommend it to kenshi who may not yet have mastered their defensive skills.  For less experienced kenshi, we might recommend our 5.5mm bogu, while yudansha-level kenshi performing lots of motodachi work may be more interested in the new Mitsuboshi Pitch bogu set.
